Abstract
A control device for an internal combustion engine with an electrically driven supercharger, the control device being capable of realizing excellent supercharging performance in the entire operation ranges regardless of gear positions. The control device has an internal combustion engine (1) mounted on a vehicle; a supercharger (11) with an electric motor (11b), supercharging the engine (1); control means (16, 21) for controlling the supercharging by the electric motor (11b); and a speed changer (27) for changing the speed of the output of the engine (1). When the gear position of the speed changer (27) is at a low position, the control means (16, 21) increases the assistance amount of supercharging by the electric motor (11b) to a level greater than at a high position. Since the assistance amount of supercharging increases as the speed stage of the speed changer (27) is lowered, transitional lowering of vehicle acceleration performance in a low speed range can be prevented, and this enables preferable supercharging effect to be obtained in the entire gear positions (entire vehicle speed ranges).

Embodiment
Mode of execution to the control gear of the internal-combustion engine with electronic pressurized machine of the present invention describes below.Motor 1 with present embodiment shown in Figure 1 with the control gear of the internal-combustion engine of electronic pressurized machine.
The motor 1 that illustrates in the present embodiment, only illustrates one of them cylinder with sectional view here for carrying the multi-cylinder engine on vehicle in Fig. 1.Motor 1 is the so-called in-cylinder injection h type engine h by the upper surface burner oil of the piston 4 of sparger 2 in cylinder 3.This motor 1 not only can homogeneous combustion, and can stratified mixture combustion.In addition, this motor 1 also can lean combustion (lean-combustion engine), by more suck supercharging airs by 11 pairs of turbosupercharger described later, to carry out lean-burn, can not only realize high outputization, and can realize low fuel consumptionization.
Open and close by intake valve 8 between the inside of cylinder 3 and the inlet air pathway 5.Exhaust after the burning is discharged to exhaust passageway 6.Open and close by exhaust valve 9 between the inside of cylinder 3 and the exhaust passageway 6.On inlet air pathway 5, begin to dispose air-strainer 10, turbo charger unit (pressurized machine) 11, interstage cooler 12, closure 13 etc. from upstream side.Air-strainer 10 is for removing the filter that sucks airborne refuse, dust etc.Turbo charger unit 11 is arranged between inlet air pathway 5 and the exhaust passageway 6, carries out supercharging.In the turbo charger unit 11 of present embodiment, turbo machine lateral lobe wheel and compressor side impeller are connected (below, this part only is called turbine/compressor 11a) by running shaft.
And the turbosupercharger of present embodiment is the turbosupercharger that the charged motivation of motor 11b is housed, and wherein the running shaft of turbine/compressor 11a is an output shaft.Motor 11b is a Wechselstrommotor, also can be used as generator.Turbo charger unit 11 can be as the common pressurized machine that is only carried out supercharging by exhaust energy, and still also can drive turbine/compressor 11a forcibly by motor 11b carries out further supercharging.
In addition, by utilizing exhaust energy, making motor 11b rotation, can generate electricity, and reclaim the electric power that is produced through turbine/compressor 11a.Although not shown, motor 11b has the rotor on the running shaft that is fixed to turbine/compressor 11a and is configured in its stator on every side as the main composition part.The downstream side of the turbo charger unit 11 on inlet air pathway 5 is provided with air-cooling type interstage cooler 12, is used to make the pressure of following the supercharging by turbo charger unit 11 to cause to rise and the temperature of the suction air that temperature rises descends.Interstage cooler 12 descends the temperature that sucks air, thereby charging efficiency is improved.
The closure 13 of regulating the suction air quantity is set in the downstream side of interstage cooler 12.The closure 13 of present embodiment is so-called electronic control type closure, wherein, detects the operation amount of accelerator pedal 14 by accelerator position sensor 15, and ECU16 (control mechanism) determines the aperture of closure 13 according to this testing result and out of Memory amount.Closure 13 is opened and closed by throttle motor subsidiary disposed thereon 17.And, can also on closure 13, be provided for detecting the throttle position sensor 18 of its aperture by way of parenthesis.
Be provided for detecting the pressure transducer 19 of the pressure (suction pressure) in the inlet air pathway 5 in the downstream side of closure 13.These sensors 15,18,19 are connected on the ECU16, and its testing result is fed to ECU16.The electronic control unit of ECU16 for constituting by CPU, ROM, RAM etc.Above-mentioned sparger 2, igniter plug 7, motor 11b etc. are connected to ECU16, and they are by the SC sigmal control from ECU16.In addition, detect the cam-position sensor 20 of cam position, the controller (control mechanism) 21 that links to each other with motor 11b, storage battery 22 etc. and also be connected to ECU16.Controller 21 is not only controlled the driving of motor 11b, and has the function of voltage transformation of carrying out the electric power of motor 11b generating as transducer.The electric power that is produced by generating is undertaken being charged in the storage battery 22 behind the voltage transformation by controller 21.
On the other hand, on exhaust passageway 6, the exhaust emission control catalyst 23 of purifying exhaust gas is installed in the downstream side of turbo charger unit 11.And, (the surge tank portion of pressure transducer 19 is set) from exhaust passageway 6 (upstream portion of turbo charger unit 11) to inlet air pathway 5 EGR (exhaust gas recirculatioon) path 24 that exhaust gas recirculation is used is set.On EGR path 24, install and be used to regulate the EGR valve 25 of exhaust gas recirculation amount.The aperture control of EGR valve 25 is also undertaken by above-mentioned ECU16.
And, the speed probe 26 that is used for the detection of engine rotating speed is installed near the bent axle of motor 1.In addition, the control valve 28 of speed changer 27 inside is accepted to drive from the signal of ECU16, carries out gear shifting operation thus.That is, the gear of speed changer 27 is grasped by ECU16.In addition, though the speed changer 27 shown in the figure also can be a manual transmission for automatic transmission (5 speed of advancing, retreat 1 speed).Under the situation of manual transmission, be provided for detecting the sensor of its gear.
The substantial section that the boost pressure that uses above-mentioned motor 11b is controlled describes.Fig. 2 illustrates the flow chart of this control.The control of flow chart shown in Figure 2 repeats every scheduled time (for example, every 32ms).
At first, detect engine speed by speed probe 26, and according to sucking air quantity (inferring by pressure transducer 19), throttle opening (detecting by throttle position sensor 18) supposition engine load (step 200).Then, calculate elementary object boost pressure B (step 205) according to engine speed and engine load.The boost pressure that so-called elementary object boost pressure B produces when being exactly the regulation engine speed of anticipation when running well, regulation engine load waits by experiment in advance and obtains and be stored in as mapping in the ROM of ECU16.
Then, according to by the engine speed of speed probe 26 detections and the accelerator opening that detects by accelerator position sensor 15, determine the boost pressure P (step 210) that increases by motor 11b.Relation between the boost pressure P of engine speed, accelerator opening and increase waits in advance by experiment to be determined, and is stored among the ROM in the ECU16 as mapping.Shown in Figure 3 should the mapping.As shown in Figure 3, here, engine speed is below the regulation rotating speed and accelerator opening is that the above zone of regulation aperture is set at specific operation range, when having only motor 1 to be in the state of running in this specific operation range, the boost pressure P of above-mentioned increase just is set at positive value, just carries out the additional mechanical supercharging that is produced by motor 11b.In specific operation range, low more rotating speed, big more accelerator opening, the boost pressure P of increase is big more.
State at motor 1 is under the situation of the state outside the specific operation range, and the boost pressure P of above-mentioned increase is zero, is negative value but be set, and comes to forbid in fact the additional mechanical supercharging that is undertaken by motor 11b thus.The meaning that the boost pressure P that increases is set at negative value describes subsequently.After step 210, detect the gear of speed changer 27, to determining correction factor K by gear.Here, determine correction factor K (step 212) according to following table 1.
Table 1
| | 1 | 2 | 3 | 4 | More than 5 speed |
| Correction factor K | 1.3 | 1.2 | 1.1 | 1 | 1 |
After correction factor K determines, calculate target boost pressure T (step 215) according to target boost pressure T=correction factor K * (the boost pressure P that elementary object boost pressure B+ increases).Can be clear that from table 1 because correction factor K, target boost pressure T is under the situation of low speed segment side (or, offside in the low speed segment side) at gear high under than the situation that is in the high regime side.
In addition, target boost pressure T is the desired value in the control of setting for the boost pressure control of motor 11b, also has and the inconsistent situation of the actual boost pressure of wanting.For example, as can be seen, in the slow-speed of revolution, when accelerator opening is big, increasing amount P sets greatly from the mapping of Fig. 3, and target boost pressure T sets greatly., target boost pressure T at this moment also has the situation of in fact inaccessiable boost pressure.By target setting boost pressure T like this, can proceed complete auxiliary (the full assist) of the boost pressure of motor 11b reliably.Particularly, be set under the positive situation, promptly at increasing amount P, when considering carry out the supercharging of motor 11b on one's own initiative, by increasing amount P, set this target boost pressure T bigger slightly, thereby can carry out the supercharging of motor 11b reliably than the actual boost pressure of wanting.
After calculating target boost pressure T, the suction tude internal pressure is detected (step 220) as actual supercharge pressure C and by pressure transducer 19, calculate the poor Δ P (step 225) of above-mentioned target boost pressure T and detected actual supercharge pressure C.Then, whether judge the poor Δ P that calculates than 0 big (step 230),, then expression is had or not the auxiliary sign Fassist of the supercharging of motor 11b to be set at 0 if difference Δ P is below 0, and the flow chart that temporarily breaks away from Fig. 2 is assisted in the supercharging of not carrying out being carried out by motor 11b.Here, though the supercharging amount P of above-mentioned increase be on the occasion of, if difference Δ P is below 0, then also do not carry out the supercharging of motor 11b.On the other hand, under step 230 is sure situation, that is, difference Δ P is than under the 0 big situation, determines to carry out the indicated value of the auxiliary usefulness of supercharging of motor 11b according to difference Δ P, and this indicated value is exported (step 235) to controller 21.
Poor Δ P shown in Figure 4 and give relation between the command value of controller 21.Shown in the solid line of Fig. 4, carry out output to the command value of controller 21 by magnitude of voltage.P is big more for the difference Δ, and then big more magnitude of voltage is sent controller 21.The scope of this magnitude of voltage here is 0～4.3V.When the voltage of 4.3V was sent controller 21, controller 21 drove motor 11b entirely, to carry out full additional mechanical supercharging.After controller 21 is sent indicated value, auxiliary sign Fassist is set at 1 (step 240), control motor 11b (step 245) according to the indicated value that controller 21 receives.
As mentioned above, the gear of speed changer 27 is in the low speed segment side more, and target boost pressure T is big more.Therefore, be at the gear of speed changer 27 under the situation of low speed segment side (or being in the low speed segment side more), (comparing with the situation of high regime side under identical conditions) difference Δ P becomes big.As a result, the voltage of supplying with motor 11b uprises, and the supercharging auxiliary materials that motor 11b is produced increases.Be at speed changer 27 under the situation of low speed segment side (or, be in the low speed segment side more) in order to strengthen the supercharging auxiliaring effect of motor, the beginning of turbine/compressor 11a is sharply rotated.Although be at speed changer 27 under the situation of low speed segment side, the rising of the engine speed during acceleration is rapid, because the rotation of turbine/compressor 11a also sharply begins as mentioned above, reduce so can prevent cambic output.
As mentioned above, be under the situation of low speed segment side (speed of a motor vehicle is low) at the gear of speed changer 27, if the acceleration of overtaking other vehicles (standard-sized sheet acceleration) etc., then engine speed reach the preceding time of maximum speed (heighten grade time rotating speed) short (with the high regime side than short).If do not carry out the correction corresponding with gear of present embodiment, then for the rising of secondary speed, because the influence of the moment of inertia of turbine/compressor 11a, it is big that the operating lag of its relative engine speed can become.
In addition, postpone to become big main cause in response, for example follow delivery temperature to reduce in addition from the heat release of the vent systems of turbine upstream sides such as gas exhaust manifold.Make the exhaust energy of the turbine rotation of turbo charger unit 11 also be subjected to the influence of delivery temperature, so, if delivery temperature reduces, the energy of turbine rotation is also reduced.And because this operating lag, existence can not make the miniaturization significantly of motor, can not improve the shortcoming that natural fuel consumes.
In the present embodiment, by carrying out the correction corresponding with gear, can eliminate above-mentioned operating lag, the transitionality that suppresses the vehicle accelerating ability energy of low-speed region reduces.And the improvement of the natural fuel consumption that is caused by miniaturization significantly also is possible.In addition, for the situation of the acceleration under the high-speed travel (gear is in the high regime side), running resistance is big, and the rate of climb of engine speed also diminishes, and result, the temperature of vent systems itself rise also high (near stablizing full load).Therefore, be in high-speed region (gear is in the high regime side more) more, the operating lag of secondary speed is more little.
And, also can restriction be set to above-mentioned correction factor K.For example, under vehicle and situation, when detecting the slippage of wheel, can apply the restriction that the size that makes correction factor diminishes with tractive force control.For the situation of wheelslip, reduce the output of motor, to suppress the slippage of wheel.Therefore, detecting under the situation of vehicle slip, suppressing the increase of target boost pressure T (supercharging auxiliary materials) by correction factor K.At this moment, can forbid the utilization of correction factor K, also can make the value of correction factor K become 80% of value definite in step 212.Perhaps, also can use correction factor K correction factor in addition.
And,, in the time of outside being in above-mentioned specific operation range, the supercharging amount P that increases is set at negative value here.By like this, calculate calculated target boost pressure T lessly, the result calculates poor Δ P lessly.Be based on that the size of poor Δ P judges owing to whether carry out the boost pressure control of motor 11b, so, for the situation of calculating poor Δ P lessly, be difficult to carry out the boost pressure control of motor 11b.Difference Δ P is the poor of less target boost pressure T that calculates and actual supercharge pressure C, so, carry out in the boost pressure control of motor 11b judging whether, as a result of, actual supercharge pressure C guarantees amplitude of fluctuation to a certain degree relatively.
So, only causing actual supercharge pressure C change, under the auxiliary situation that the beginning of not looking on the bright side of things is carried out by motor 11b, the supercharging of motor 11b become be difficult to carry out, thereby can stably carry out boost pressure control by external disturbance etc.For example, since external disturbance etc., actual supercharge pressure C carry out repeatedly under the situation of small increase and decrease change, if repeat continually the supercharging carried out by motor 11b begin stop, then boost pressure control is chaotic on the contrary.That is, carried out controlling by the unnecessary boost pressure that motor 11b carries out.Therefore, considering unnecessary when carrying out the supercharging of motor 11b (beyond specific operation range time), be difficult to begin to realize the stabilization of boost pressure control by the supercharging that makes motor 11b.In addition, above-mentioned mode of execution is the mode of execution of " the supercharging auxiliary materials that makes above-mentioned motor is increasing under than high situation under the low situation of the gear of speed changer ", and, mode of execution for " compare with high situation; the gear of speed changer is low more, the supercharging auxiliary materials of above-mentioned motor increases more ".
In addition, the invention is not restricted to above-mentioned mode of execution.In the above-described embodiment, though the control gear of the internal-combustion engine with electronic pressurized machine of the present invention is applicable to directly jetting gasoline engine,, the present invention also goes for the petrol engine of non-straight spray or diesel engine etc.And though in the above-described embodiment, pressurized machine is a turbosupercharger, can not be turbosupercharger also, for example can be remove that the exhaust side of turbosupercharger of charged motivation is such, DYN dynamic compressor etc.In addition, in the above-described embodiment, though calculate target boost pressure T according to target boost pressure T=correction factor K * (the boost pressure P that elementary object boost pressure B+ increases), but, also can calculate target boost pressure T according to target boost pressure T=elementary object boost pressure B+ (the boost pressure P * correction factor K of increase).
Industrial applicibility
The control gear with the internal-combustion engine of electronic pressurized machine of record according to the present invention, owing to make the supercharging auxiliary materials be under the situation of low speed segment (or being in low speed segment more) at speed changer than increasing under the high situation, so can suppress the transitionality of the vehicle accelerating ability energy in the low-speed region reduces, thereby can in whole gear (that is, whole the speed of a motor vehicle zone), obtain good pressurized effect.
